2001 Sundancer 260 7.4MPI
Installed new fuel pump, old one seem to be failing, intermittently working. New one installed, boat fired right up, ran it on and off a couple times while sitting on trailer with muffs. Towed to boat to ramp and dropped in, started at dock and sputtered out after a couple min. Cycling key, I could no longer hear the fuel pump coming on, but I could hear the relay clicking on and off. Cycled key about 15 times, could not get fuel pump to come on. Pulled boat back out of water, unplugged fuel pump and reconnected, checked ECM connections, cycled key, pump came on and boat started. I'm leaning towards possible bad ground? Is there also an oil pressure sensor that could be going bad and cutting fuel?
Grabbing a friends scanner to check for codes, no abnormal beeping from alarm. Just 2 beeps when turning key on.
